Image

Check if the input value is a file and the file type is an image.

The validation rule requires a value to run.

Example​

src/app/posts/controllers/create-post.ts
// ...
createPost.validation = {
  rules: {
    title: ["required"],
    image: ["required", "image"],
  },
};

It works also if the input is an array of images:

src/app/posts/controllers/create-post.ts
// ...
createPost.validation = {
  rules: {
    title: ["required"],
    images: ["required", "image"],
  },
};
